"405 Method Not Allowed" only in Firefox 6 but not in IE 9 when calling WCF service

I have a WCF service hosted on http://localhost:8080, and a web application on http://localhost:82. I have Windows 7 64-bit and IIS 7.5.

The pages in the web app makes AJAX requests to the WCF service using jQuery.

In IE, the service calls perform fine. In Firefox, I get a 405 Method Not Allowed error. The service calls that the web application makes from the ASP.NET code-behind always succeed.

Other developer's builds are having the same problem. I initially thought it had to do with cross-site security restrictions that were introduced in FF 3.5, based on this article: https://developer.mozilla.org/En/HTTP_access_control. However, after adding all the response headers I appeared to need, the problem still occurred.

I've run the aspnet_regiis.exe command, and the WCF ServiceModelReg.exe command as well.

Here is the request that Firefox makes:

OPTIONS http://localhost:8080/ScoutService.svc/Contact_Add HTTP/1.1
Host: localhost:8080
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:6.0.2) Gecko/20100101 Firefox/6.0.2

Connection: keep-alive
Origin: http://localhost:82
Access-Control-Request-Method: POST
Access-Control-Request-Headers: content-type
Pragma: no-cache
Cache-Control: no-cache

Here is the response from the server:

Any ideas?

Firefox sends an OPTIONS request in addition to a POST or GET.

See http://forums.iis.net/t/1160649.aspx for how to fix it.

Edit

The other thing that is special in your case is that you are using IIS 7.5 which does not allow all verbs by default.

You need to allow the OPTIONS verb

IIS 7.5, Web Service and HTTP 405 error
